Abstract

The title compound, C(20)H(16)O, (I), which crystallized exclusively as its ap rotamer, exhibits several intermolecular aryl-H.pi(arene) interactions, resulting in planar molecular arrays in which each molecule interacts with six adjacent molecules. Surprisingly, there were no O-H.O-H or O-H.pi(arene) interactions within hydrogen-bonding distances. Crystalline (I) melted sharply without molecular decomposition (NMR), but the cooled melt recrystallized only after several hours.
